According to Greek mythology the lustful nature of Zeus led him to lie with Mnemosyne, a Titanide daughter of Gaia (Earth) and Uranus (Sky), goddess of memory and remembrance. He spend with Mnemosyne nine nights in Pieria region close to Olympus Mountain. As a result of this coupling, Mnemosyne did give birth to nine daughters, on consecutive days. One of these daughters is Erato  the Muse of lyric poetry, particularly erotic poetry, and mimic imitation. The name would mean “desired” or “lovely”.
